Background technology
With the development of science and technology, cities in China Feasibility of developing track transportation, subway, light rail have become the weight of people's trip
The vehicles are wanted, alleviate the traffic blocking problem run into current city.Due to traditional rail vehicle such as subway, light rail car
Seat major part in is fixing seat, and occupancy guest room area is larger, at phase commuter rush hour, because seat can not move,
Larger space is occupied, so as to cause that substantial amounts of passenger can not be accommodated in guest room.It is only few in existing subway, light rail seat
Part is Collapsible seat, after seat is folded, is only capable of vacateing a small amount of space, can not meet the passenger capacity of phase commuter rush hour
It is required that and rumble seat can not generally realize the locking being laid flat or during folded state, stability is poor.
Have to the method that rumble seat is improved a variety of, patent CN 104802814B disclose a kind of trolley coach and turned over
Swivel base chair, including seat, backrest, the both sides of backrest are provided with connection metal plate, connect the chute that arc is provided with metal plate, seat
It is flexibly connected with chute by rotating shaft, it is necessary to manually rotate counterclockwise dead bolt with key during swiveling seat, dead bolt pulls steel wire rope
Stay rotates counterclockwise in drive, extension spring, while in the presence of gear, upper stay drives lower stay clockwise
Rotate, vacate chute and supply pivot, complete seat rotation, but manual operation wastes time and energy, it is complicated.Patent CN
107139956A discloses a kind of novel track Vehicular electric passenger seat, including seat, backrest and latch-up structure, backrest
Both sides are provided with connection metal plate, and locking mechanism is arranged on connection metal plate, and seat and backrest are flexibly connected by rotating shaft, by turning
Axle realizes the upset of seat, by gear ＆ rack structure, realizes automatic locking and unblock, but complicated.
The content of the invention
In order to solve existing technical problem, the invention provides a kind of novel track folding seat for vehicle, pass through chain
Wheel chain drive realizes that cushion is overturn, and rear locking in place, and reliability is high, in light weight, carrying is big.
The technical scheme is that；A kind of novel track folding seat for vehicle, including backrest, cushion, sprocket wheel, chain
Bar, limit switch and control structure；The backrest and cushion are flexibly connected by cushion moving axis；The sprocket wheel, chain and spacing

Further, the upside of the backrest sets indicator lamp, and indicator lamp is electrically connected with the controller.
Further, install sensor, sensor are electrically connected with the controller on the limit switch.
In use, driver presses opening button in drivers' cab, controller work, the lock function of brake is closed, is braked
Device does not fix motor, the work of controller controlled motor, and motor drives multi-diameter shaft to rotate clockwise by shaft coupling, and multi-diameter shaft drives
Minor sprocket is rotated, and chain tension, minor sprocket are driven chain to be driven clockwise by tensioning wheel, and chain-driving big sprocket wheel rotates, big chain
Wheel drives cushion moving axis to rotate clockwise, and drives cushion to downwardly turn over opening, raised to rear side as chain is driven clockwise
Limit switch is moved, and when cushion is fully flipped open downwards, raised rear side is stuck on limit switch, the biography installed on limit switch
Sensor sends signal, and controller receives signal, and controlled motor is stopped, and opens the lock function of brake, and brake is solid
Determine motor stalling, prevent motor from working, locking cushion；Driver presses folding button in drivers' cab, controller work, closes braking
The lock function of device, brake do not fix motor, the work of controller controlled motor, and motor drives the multi-diameter shaft inverse time by shaft coupling
Pin is rotated, and drives minor sprocket to rotate, and chain tension, minor sprocket are driven chain to be driven counterclockwise by tensioning wheel, the big chain of chain-driving
Wheel rotates, and big sprocket wheel drives cushion moving axis to rotate counterclockwise, and drives cushion to be flipped up folding, as chain is driven counterclockwise,
The raised limit switch to front side is moved, and when cushion folds fully up, raised front side is stuck on limit switch, on limit switch
Sensor send signal, controller receives signal, and controlled motor is stopped, and opens the lock function of brake, brake
Fixed motor stalling, prevents motor from working, locking cushion.
Cushion upset is opened or barrier is run into during folding, and cushion stops upset, and sprocket wheel can not rotate, and motor is defeated
Go out electric current increase, controller receives motor signal, after controller control cushion withdraws 5 ° -20 ° of angle, rests on current shape
State, controller control indicator lamp flicker alarm, until after barrier excludes, presses and opens button or fold button, sit again
The normal upset of pad.
When compartment powers off, by short circuit braking key insertion brake and rotate, close the lock function of brake, turn manually
Dynamic cushion, short circuit braking key is then rotated, open the lock function of brake, locking cushion.
Using above-mentioned technical proposal, what the present invention realized has the beneficial effect that：
(1) present invention realizes the automatic turning of cushion by the way of sprocket wheel chain drive, and reliability is high, simple in construction.
(2) using limit switch and the raised locking for judging cushion in place, and combining brake progress cushion, locking can
Lean on, higher moment of torsion can be born, and in the case of compartment power-off, can manual overturning cushion and locking.
(3) automaticity is high, and using the button of drivers' cab, cushion auto-folder or opening can be achieved, in place rear locking,
The course of work operates without crew, time saving and energy saving.
(4) present invention is compact-sized, and slight high, in light weight, seat can bear 6 people's weight.
